one hub did characterize the incorrect memory network: inferior frontal gyrus, pars orbitalis (IFOr). As shown in the node hierarchy in Figure 2B and in the bar graph in Figure 2D, this region of prefrontal cortex had increased participation during incorrect rather than correct retrieval (χ2 (1) = 20.02, pcorrected < 0.05). Past research has implicated the inferior frontal gyrus in suppression of prepotent responses9, and it is intriguing to consider that heightened influences of this subarea during retrieval could indicate inhibition of other circuits relevant to correct retrieval.
